Incredible new item! These are Mason jar strainer and shaker lids made from STAINLESS STEEL! Ditch the plastic!  Best of all, it's a 2 PACK! These rust-proof lids are for regular-mouth Mason jars. Make a dressing or infuse oil with fresh herbs and strain as you pour! Great for straining ice, making mixed drinks, and more. See fit chart in photo.  *Mason jars are not included.  You are getting two strainer lids, each comes with it's own lid so if you want to use it as a shaker, there ya go.
